Thanks for the link to this pdf as I have been getting a little worried about my eyesight as I have become older. I am not certain but it seems to have become just a little bit blurry from a distance. I want to make sure I am still 20/20.
Well, you are free to test your vision with the Snellen. Just remember that even if you do have worse than 20/20 you CAN improve your vision—which just so happens to be what this site is all about!
